  • Abstract

    Two Schiff bases 9H-carbazole-3-carbaldehyde-4-phenylthiosemicarbazone (CCPTSC) and 2-thiophenecarboxaldehyde-4-methylthiosemicarbazone (TCMTSC) were synthesized. Both the CCPTSC and TCMTSC were characterized by elemental analysis, molar conductivity studies, Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (NMR), and x-ray powder diffraction (XRD). All the spectral studies confirmed that the formation of both CCPTSC and TCMTSC. Thermal stabilities of the both Schiff bases were reported based on thermogravimetric analysis (TGA) studies.
